 To use, run
 
 ```bash
-npx create-react-sandbox react-sandbox
-cd react-sandbox
+npx create-react-sandbox
+cd app
+npm start
+```
+
+The sandbox app will run on [http://localhost:3001](http://localhost:3001) (or if you have a `PORT` environment variable set, it will run on that instead).
+
+To build your code, run `npm run build`. The build output will be in the `dist` directory.
+
+## Configuration
+
+To set the name of your sandbox, use the `--name` option.
+
+```bash
+npx create-react-sandbox --name project-name
+cd project-name
 npm start
 ```
 
 If you would like to use TypeScript in your project, run with the `-t` flag.
 
 ```bash
-npx create-react-sandbox react-sandbox-with-typescript -t
-cd react-sandbox-with-typescript
+npx create-react-sandbox -t
+cd app
 npm start
 ```
 
-In either case, the sandbox app will run on [http://localhost:3001](http://localhost:3001) (or if you have a `PORT` environment variable set, it will run on that instead).
+To add [Eslint](https://eslint.org) support, run with the `-l` flag.
 
-To build your code, run `npm run build`. The build output will be in the `dist` directory.
+```bash
+npx create-react-sandbox -l # or `npx create-react-sandbox -t -l` for ts and eslint support
+cd app
+npx eslint
+npm start
+```
